Meet Bubbl — the water tracking app that gives you a reason to actually drink water. Your fish lives in your phone. When you stay hydrated, it swims happily around its tank, unlocks new friends, and shows off its custom colors. When you forget to drink? It flops dramatically on the sand and judges you. TRACK YOUR WATER YOUR WAY Log water in seconds with quick-tap presets, custom amounts, or our AI bottle scanner — just point your camera at any water bottle and Bubbl identifies it and logs the exact amount automatically. A FISH THAT NEEDS YOU Your fish reacts to everything. It spins when you log water, flops when you’re dehydrated, blinks lazily when it’s bored, and swims freely around its tank. Tap it and it’ll spin for you. It’s alive. Don’t let it down. UNLOCK A WHOLE SCHOOL Build your streak and unlock 10 unique sea creatures — from your starter pufferfish, clownfish, and angelfish all the way to a shark, octopus, jellyfish, seahorse, starfish, swordfish, and manatee. Each one is fully customizable with your own color combinations. COMPETE WITH FRIENDS Add friends, track each other’s streaks on the leaderboard, and send taunts when they fall behind. Nothing motivates hydration like a little competition. BUILT FOR REAL LIFE ∙ AI-powered bottle scanner identifies your water bottle automatically ∙ Daily streak system keeps you coming back ∙ Custom hydration goals in oz or liters ∙ Push notification reminders ∙ Dark and light mode ∙ Designed for all ages with full COPPA compliance for younger users Drink water. Keep your fish happy. Build your school.
